摘要

描述了一种从测量的终端电压和电流估计异步电机速度的方法，用于无速度传感器矢量控制。该方法简单，对电机参数的变化具有较强的鲁棒性。这种方法不依赖于定子电阻值的知识，也不受定子电阻热变化的影响。传感变量的纯积分，原则上，是不需要的。因此，这种方法可以实现比以前的无转速驱动器更宽的带宽速度控制。仿真和实验验证了该技术的有效性

Robust speed identification for speed sensorless vector control of induction motors

An approach to estimating induction motor speed from measured terminal voltages and currents for speed-sensorless vector control is described. The proposed technique is very simple and robust to variations of motor parameters. This approach is not dependent upon the knowledge of the value of the stator resistance, nor is it affected by stator-resistance thermal variations. Pure integration of sensed variables, in principle, is not required. Therefore, this method can achieve much wider bandwidth speed control than previous tacholess drives. The effectiveness of the technique is verified by simulation and experiment.<>
